Been fancying the Castelli Alpha Jersey for a while. The jacket is nice too, but I run too hot for that. Anyway, I managed to get the Jersey for a steal and it arrived today. Won't say the price, as it's now sold out. Weather has been very changeable as you know, so decided to get a quick Blast to test it out. Everything from direct sunshine, at about 15 degrees, to hailstones and heavy rain at 8 degrees. All this with heavy wind and in the space of 25 mins and 10 miles. At the warmer end, I didn't overheat like I normally do, due to the breathable rear of the jersey. The wind failed to have any effect whatsoever, due to the windstopper front and arms, despite being 20mph plus. The rain and hailstones didn't seep through either the front or the back. Absolutely superb piece of kit. I honestly think that it's worth the full RRP if I am completely honest! Today was with a very light SS mesh base layer. My Winter will be with a LS thicker base layer at the very most. Fit is fairly aero, but slightly more relaxed than the Gabba. The only minor points were that the sleeves are a tiny bit long and ever so slightly lose at the bicep. Clearly need to work on that area it appears! When on the bike, the sleeve length is less of an issue and the small amount of spare bicep fabric doesn't flap anywhere near as much as I expected. Just goes to show that they design it for riding position and not standing up in front of a mirror! Overall, a huge result!
